Letters Patent No. 98,769,

dated January 11, 1870.

IMPROVED PESSARY.

The Schedule referred to in these Lettera Patent and making part of theam To all whom it may concern Be itknown that I, Euxsr F. Hermann, otthe city, county, and State of New York, have invented a new andusefnlImprovement in Pessaries; and'l do hereby declare the following to be afull, c1ear,.and exactdescription thereof, which \villenable thoseskilled in the art to makeand use the same, reference beingspecification, in which drawing.

Figure 1 is a top view of a pessary, containing my invention.

Itigure 2 is a partial under-side view.

Figure 3 is a transverse section, in the line a: x of iig. 1.

Similar letters indicate corresponding part-s.

My invention is an improvement on the device for which Letters Patenthave been previously granted to me, and consists in combining, with saiddevice, a sac or covering over the bottom'thereof.

The letter A designates the pessary in all three figures. Its walls aredouble, so as to enclose a hollow space, H, which I fill with air, atsuch pressure as I desire, sufiicient to maintain the pessary in propershape under the pressure of the atmosphere or external air; or, ifdesired, the p'cssary may he made solid, and of any suitable material.

Below the anterior edge of the pessary, I make the surface recedebackward, as shown at 1*; so as to allow the anterior'wall of the vaginato approximate the posterior wall almost immediately in front of theposition after the pessary is in place.

The concave surfaces are represented atb c, and the elevation at d.

All these features were secured in my formerpatent, and I do not nowclaim them.

In order to apply my pessary, in the treatment of ulceration of theuterus, inflammation, Ste, I combine therewith a covering or sac, G,arranged about or around the mouth or the bottom of the opening E. Thiscovering or sac forms an extension of the sides of the opening, and Imake it of thin, flexible material, such, for example, as .thin Indiarubber, and it constitutes a small sac, which can be filled with cotton,sponge, or other porous or absorbent material,

saturated with the proper remedial agent, or the sac may be filled withany ointment or liquid which it is desired to apply to the uterus.

If it is required to apply a remedy in liquid form, I firstf'apply thepessary, and then, by means of actorine syringe, whose point has beenbent to a suitable angle, inject the liquid into the sac.

This portion of my invention enables the physician to make localapplications with good efl'ect, without injury to the neighboring parts.

What I claim as new, and desire to secure by Letters Patent, is-

The pessary, consisting of the parts I: c d, in combination with the sacor covering over the bottom,

. substantially as and for the purpose described.

This specification signed by me, this 31st day of I August, 1869.
